This setting:
config.getAppContext().put(DataEngine.MEMORY_BUFFER_SIZE, birtProperties.getBirtMemoryBufferSize(key));
sets the max memory used per query before caching to disk. It defaults to 10 MB. What are you setting it to?

We do not have any cross tab reports.Could you please suggest what needs to be set to remove all data caching as its occupying more space and reports are erroring out with exception: No disk space left.

The exception attached in file occurs intermittently and not sure about the root cause.

Is there any implication if we delete DataEngine while the report generation is in process.

Have you tried putting a higher value in
config.getAppContext().put(DataEngine.MEMORY_BUFFER_SIZE,
birtProperties.getBirtMemoryBufferSize(key));

I believe this will cause problems if you delete the files.
